Anyways, there are machines for several different purposes. Only spend big if you know you will use the machine fully and for a long time.
>trapping and off trail useget a wide track and carry a rope winch and shovel. Four strokes and efi highly recommended so you don't get stranded.
>recreational trail useanything works for this, but lighter sleds are more fun and easier to unstuck. Carry a shovel
>transportation/haulingfour stroke efi is quiet reliable, and has a wider power band for hauling. A low gear and reverse is needed for a lot of hauling. Wide track if you want to do a lot of hauling. Also consider the heavier the sled, the more tractive effort you have on the trailer, but the harder it is to get unstuck. Carry a rope winch and shovel. Heavier sleds also have a nicer ride quality.
>deep snow and mountainI dont have much experience with this, but you want a light sled with a lot of power and big lugs/ a long track. Ride with friends.
In any case, you need to detail where and what type of riding you will do.
Also, talk to a dealer/salesman. They know what people buy for what purposes, have experience themselves, and often sell used machines at a small premium over craigslist.
